Property descriptions
Runtime.MemoryUsed
MemoryUsed As UInt64
Returns the total amount of memory used (in bytes) by the allocated objects.
This property is read-only.
More specifically, this returns the number of malloc'd bytes. Since the OS does not immediately give back memory after it is released there is no guarantee that this number will match OS values that you see in Activity Monitor, Task Manager or top.
Runtime.ObjectCount
ObjectCount As Integer
Returns the current number of objects in existence.
This property is read-only.
Method descriptions
Runtime.IterateObjects
IterateObjects As ObjectIterator
Iterates over the objects in the Runtime environment. Use it to get the TypeInfo for each object. See the ObjectIterator class for an example.
Runtime.ObjectClass
ObjectClass(index as Integer) As String
ObjectClass returns the class of the passed object.
This property is read-only.
The index must be greater than or equal to zero and less than the ObjectCount.
Runtime.ObjectID
ObjectID(index as Integer) As Integer
ObjectID returns a unique identifier for the passed object.
This property is read-only.
The index must be greater than or equal to zero and less than the ObjectCount.
Runtime.ObjectRefs
ObjectRefs(index as Integer) As Integer
ObjectRefs returns the number of references to the passed object.
This property is read-only.
The index must be greater than or equal to zero and less than the ObjectCount.
Sample code
The following code displays the properties related to individual objects in a multicolumn ListBox and the total amount of memory used in a TextField:
Var lastObjectIndex As Integer = Runtime.ObjectCount - 1
For i As Integer = 0 To lastObjectIndex
Listbox1.AddRow(Runtime.ObjectID(i).ToString)
Listbox1.CellTextAt(ListBox1.LastAddedRowIndex, 1) = Runtime.ObjectClass(i)
Listbox1.CellTextAt(ListBox1.LastAddedRowIndex, 2) = Runtime.ObjectRefs(i).ToString
Next
TextField1.Text = Runtime.MemoryUsed.ToString
Compatibility
All project types on all supported operating systems.
